To all whom t may concern:

Be i. .known that I, LOUIS H. PERLMAN, a citizen of the United States, residing at New York, in the county of New York and State ofy New -York, have invented certain new and usefullmprovements in Wheels; .and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others, skilled .l0 in the art to which it appertains to make and luse the' same.

This invention relates to improvements in demountable rims for automobile wheels, and more particularly .to thetype known as transplit or crcsscut, that is, the type wherein an otherwise continuous tire-'carrying ring is transversely cutfor enablingv the rmg to be relativelyY reduced in effective diameter for permitting the application and removal 0f tires having inextensible beads.-

Thev object in viewvis 'the provision of simple and effective means whereby the afl- `joining ends of a transplit rim may be readily secured or detached. f

With this and more detail objects in view, as will 'in part hereinafter become apparent and in part be stated, the invention com- .prises certain novel constructions, combinations and arrangements of parts as 'subsequen/tlyfspecified and claimed.

f" fIn the accompanying drawingsr- .Figure 1 is a fragmentary plan view look- .ing` at the outer lface of the rim.

ig. 2 is a similar view looking at the inner face of the rim.

Fig.' 3 is a'sectional view taken on the plane indicated by line v3-3 of Fig. 2.

Fig. 4 is a sectional view Vtaken on the plane indicated by line 4--4 ofFig. 2.

Fig. 5 is a perspective view of the latch .plate detached. Fig. 6 is a view similar to Fig. 1 of a slightly modified embodiment of the invention.

Fig. 7 is a perspective view of the latch plate employed in the structure seen in ig. G.

Fig. 8 is a perspective view of the retain-v ing-button detached. eferring t0 the drawing by numerals, 1

indicates a demountable rim of the usualcross-cut type, the rim being cross-cut at the point 2, leaving rim terminals 3 and 4.

A latch plate is connected to terminal Specication of Letters Patent.'

to engage terminal 4. The said latch plate conslsts of a tongue 5,' which, as illustrated, comprises a strip of metal, but may be formed otherwise when preferred.. The tongue 5 is constructed with 'outstanding shoulders 6, 6, at one endjand' an'enlarged portion extending-substantially at right angles with the mam part 'of lthe tongue `at the other.

The latchplate 5 is electrically welded,v

riveted o r otherwise fixed. to the youter surface of rim .1, at the' terminal 3, land extends from terminal 3 to and `into engagement with Patented nec. 10,1918. i Application mea una is, 1917-. serial no. 156.532.' Y

terminal 4 as will hereinafter be clearly explained.' The terminals of rim .1 are `formed offset, asat 8 and`9, by stamping or any other appropriate means,l the said offset being suliiciently depressed to allow the tongue .5 to have vits outer surface lie ilushwiththe outer surface of the baseof rim 1. LT he reej end portion 7 oflthe tongue 5 when applied to lthe 'rim isl positioned in-the aperture .1 0..

and abuts the offset portion of theirim` f or' latchingv .or ,retaining-the ends of rim 1 in theirrelatively, closed relation. The oifset 8 terminatesv at one of its ends along the cut line Qand atthe other end the offset is sev eredpfrom thematerialo'f the base of rim 1, along the line 11 corresponding in contour tc the end portion of tongue 5.and having the shouldered projections .6', 6 corresponding 'to theshoulders 6 and on which th proJectio'ns forming shoulders 6 lie flat.

r -..In order to relieve the stress placed on the securing means yattaching the latch plate `5 to the offset portion 8 of the rim terminal 3',

'the outstanding shoulders 6, 6, are so positioned against lthe opposite edges of theoflset 8 as to deliver stresses directly to the rim end 3 and thus proportionally relieve. the weld or other means of connection -of tongue 5 with oi'set ortion 8.

' As clearly seen in Fig. 3, the projection 7 is not exactly at right anglesto the tongue 5, but is slightly inclined and the ed eof odset 9 along the opening 1 0 is similar y incllned so as to form an eifective locking'connection between the parts.

In Figs. 6 and 7 I have illustrated a slightly modified emhodimentinwhich the tongue 5, corresponds with tonguet above described, and is provided with the shoulder portions 6-engag1ng theterminal 3'! of rim 1 which rim. is cross-cut at 2*. .The tennif susV nal 4 of said rim islrecessed at 10 for re- Vet v the ends of the recess are extended laterally beyondV the planesof the edges of tongue 5*11 and fprmed with abrupt shoulders corresponding in contour to the. shoulders engaged bythe shoulder portion 6". Extending latorally from the tongue 5n at the ends of the projections 7' are extensions or shoulder portions 7a fitting the terminals' of the aperture 10. This modified embodiment thus conforms in all details to the embodiment above described except that the free end ofthe latch is provided with lateral projections adapted to serve as additionalstress distributing members for delivering stresses` to the rim terminal La in addition to those delivered bv the projection 7a.

In operation, the rim 1 is collapsed or distorted axially as preferred for the removal and application of a tire as is well under' stood in the manipulation ot' cross-eut demountable rims. y

While the structures'above described are complete Vas described and are adapted f or effective operation, it has been found desirable under" certain conditions to provide means foi-preventing accidental withdrawal of the projection 7 from the aperture 10, and tothisend I employ a plate 15 mounted to serve as a turn-button. The plate 15 is pivoted at 16 to the rim 1 in position for having one of its ends swing to and from a location in engagement with a groove 17 formed Vin the projection 7. YTo prevent undesirable pivotal movement of the plate 15, 'the plate is formed at that face which contacts with the inner faccof rim 1 with a recess 18 engaged by a projection 19 formed on the rim 1. The said projection and recess may be formed by the use of a punch and when the two are interlocked, as indicated in Fig. 3, the plate. or button will be held against dislocation. 'hen it isdcsired to disengagethe button Afrom the projection 7 a tool is placed in a notch 20 formed in the edge of plate 15 and the plate is caused to move pivotally by the pressure of suchtool. The tool may be driven by hammer blbws if found' necessary.
